ASICCTL, CTI External Multiplexer Control register

The ASICCTL characteristics are:

Purpose

Can be used to provide IMPLEMENTATION DEFINED controls for the CTI. For example, the register might be used to control multiplexors for additional IMPLEMENTATION DEFINED triggers. The IMPLEMENTATION DEFINED controls provided by this register might modify the architecturally defined behavior of the CTI.

Note

The architecturally-defined triggers must not be multiplexed.

Configuration

It is IMPLEMENTATION DEFINED whether ASICCTL is implemented in the Core power domain or in the Debug power domain.

If it is implemented in the Core power domain then it is IMPLEMENTATION DEFINED whether it is in the Cold reset domain or the Warm reset domain.

This register must reset to a value that supports the architecturally-defined behavior of the CTI. Changing the value of the register from its reset value causes IMPLEMENTATION DEFINED behavior that might differ from the architecturally-defined behavior of the CTI.

Other than the requirements listed in this register description, all aspects of the reset behavior of the ASICCTL are IMPLEMENTATION DEFINED.

Attributes

ASICCTL is a 32-bit register.

Field descriptions

The ASICCTL bit assignments are:

313029282726252423222120191817161514131211109876543210
IMPLEMENTATION DEFINED

IMPLEMENTATION DEFINED, bits [31:0]

IMPLEMENTATION DEFINED.

Accessing the ASICCTL

ASICCTL can be accessed through the external debug interface:

ComponentOffsetInstance
CTI0x144ASICCTL

This interface is accessible as follows:

  • When IsCorePowered(), !DoubleLockStatus(), !OSLockStatus(), AllowExternalDebugAccess() and SoftwareLockStatus() access to this register is RO.
  • Otherwise access to this register is IMPDEF.
